l IMPRQ-VED MACHINE FCR PAGING BOQKS.

SperiYc-n! ion forming part of Leiters Patent No. 10,435, dated January3l, 1554.

Be it know n that I, EDWARD Town, Aof Jersoy City, State of N ew Jersey,have invented a new and useful Machine forNunibering the lagesofBlank-Books and for other Purposes;

.and Ido hereby declarcthe following .to bea -full descrilnion of thesaine.

'lhfe nature of my invention consists in arranging' in a suitable frameone or more cylinthe endofthe shaft, so that as theworm lat the oppositeend ofthe shaft draws forward the cylinders the cog-wheel slipshorizontally on it.,

This cog-wheel is operatedby two pawls-a talteu p an d h old fastpawl-the former secu red on a shaft which is operated by a foot-lever,which also operates a stainper-lever at the top ofthe machine, fortaking au impression of the,

number as it is presented on the cylinder through an opening,r intheguide-plate.

l3nt to describe niy invention more fully, I will refer to theaccompanying` drawings,forin ing a partei' this schedule, the saineletters of reference,wherever they occur, referringto the saine parts. lr

Figure l. is a plan view ofthe machine. Fig. 2 is a view ofthefront'elei'ation of the inaehi ne. Fig. 3 is view of 'the'vend elevationofthe niaychineshowi ng` the cog-wheel, pawls,and levers for operating`the saine.; Fig. 4 is a detached v icw ofthe cog-wheel and a sectionofthe shaft,

showing the groove in it for holding the cog. wheel from slipping" roundon it.

Letter A is the fraineof the machine, which mayl be made o'i' wood orniela'l, as found most advisable, and having on the upper and front sideofit a table-hoard, lL for holding` the book during the operation ofnumbering it.

Horizontally across the franie is arranged a, type-cylinder shaft, C,having on one end a screw-thread eut, and working;` in a female screw,l), secured to the frame ofthe machine.

(See detached view, Fig. 2.) 0n the opposite `cud of the' shaft isplacedacog-wheel, E, which is held from turning` round on the shaft by a-at one end pin, holding im groove, E, @un horizonmny in the end of theshaft. The object of this is to allow the cog-wheel to slip horizontallyon the type-wheel shaft as it is drawn forward by t c.

D, in consequence of the rotating female screw motion caused by thetaking-up motion of 'a pawl, G, acting on one side of theeog-wheel, andwhich is .held `from going back again by a holdfast-'pawh H, operatingon theopposite side of the cog-wheel. The pawlGis secured at `its lowerend to a lever, I, arranged on a foot-lever rod, J,extendinghorizontally across the machine, so that as the foot-lever K isoperated the pawl also is operated to take lup a tooth on the cog-wheel.

the teeth of the wheel, and letter contact with byv a center-pin, m,between the twopawls, and

tongue-piece, N, so that-when it is' desired to A throw both of thepawls out of gear the tonguepieee N is drawn down, so'as to braceagainst a stud. n, in the holdfast-pawl H, `and thereby keep `the pawlsdistended till the type-wheels may be turned back again to thel numberrequired, and for 1lnki-ng the same.

Letter P is a rod J", having at the outer end of it connection with avertical rod, R, for communicating niotion to the stalnpers S S,throughthe leVe'rT', secured on a rod, U, to which is also secured theends of the sianipcr-franie V. In `the back. end of the lever T is anadj nsti 11g-screw, XV, the

' point of which rests in aseat in theupper end of the vertical rod R,so that by the set of the l screw the pressure ofthe st-ainpers may beregu lated'. I Lette-r Xis a guide-plate,fhaving a hole eut' in itof thesize ofthe face of atype, so that as the corner of the page is presentedbutone ing rods E'. face ofthe type-wheels Z Z. 'lhesetype-wheels aremade of wood or metal, as may be required,

and secured on thel shaft C. YOn their periplifl' cries are arranged',in corresponding subdivisions with the teeth of the cog-wheel, a series`of numbers iu numerical order, or otherwise, as may he desired. i

ln the inachfne e forty-two divisions of the circumference ofthe L L aretwo springs' for holding against the pawls 'to keep them in tothetake-up 'pawl G by a pin, g, and having at the other end an adjustable.v

lever secured tothe foot-lever t l herein described there are l e negrascylinders, which wind spirally round the cyl-y inder live times. Thenumber of spiral turns 0n the cylinder may be increased to any number.These numbers may be eut in the -faee of the cylinders, or maybe typeinserted in the face of them, or may be made of stereotypefplates, andadapted so as to form adjustable plates, that variety may be substitutedinthe process of numbering the pages of books or other articles.

Theoper'ation of' my invention is that when prepared to page a book theoperator throws the pawls out of gear by putting down the tongue-piece Non the extension-brace M against the stud a on the pawl H. He then turnsthe type-cylinders back to the number required, when he" removes thetongue N and lets'the pawls fall into their places again, Wh ere they`are held by the sprmgs back of them.

\ Of the paper, to take an impression of the re- 'Wired number. Havingtaken the impression of the number, the foot-lever is released, and thespring (or gravity, as may be adopted) under the lever l) draws back thestainpers, and at the same time the take-up pawl moves the cog-Wheelround one tooth and the typef cylinder one subdivision for a 'newnumber, and spirally forward by means of the screw on the end of thetype-cylinder shaft, so that on the type-cylinder making onerevolutionit A has changed to the second column of iig nres.

The inking process may be done at tlietimc of printing, or maybe done bythrowing the? pawls ont of gear and giving the cylinders a turn `or twoagainst anvordinary inking-rollerQ-If- Having now described 'myinvention, I will, i

proceed to state what I claim and desire to sei cure by Letters Patentof the United States. What I claim there-fore is- 1. The arrangement oftype in spiral eolumns around `a cylinder for the purpose of printingsuccessive numbers, the cylinder he ing moved ylaterally while it revelves by means Y of a screw on the end of its shaft, substantially asdescribed.

2. The right to use any number ofeylinders on a single machine for thepurposes set forth.
